DT ajax error

Hello, I would like to ask you for help.

Im getting io.undertow.server.TruncatedResponseException: null and I have no idea how to fix it.

Im using container proxy 0.8.8 and ShinyProxy 2.5.0

I saw that a similar problem has already been solved here, but unfortunately this solution did not help me.

Thank you a lot

Thank you for explanation!

Yes, I modified Java code of ShinyProxy with added controller class this it whole method:

@RequestMapping(value = "xx/{xx}/{xx}/{xx}/{xx}", method = RequestMethod.POST, params = "action=DEACTIVATE")
  private String deactivateRole(ModelMap map, HttpServletRequest request, @PathVariable String xx, @PathVariable String xx, @PathVariable String xx, @PathVariable String xx, @RequestParam(value = "action", required = true) String action) {
      User user = (User) SecurityContextHolder.getContext().getAuthentication().getPrincipal();

      if (!isAdmin(user)) {
          return "redirect:/error_custom/";
      } else {

          Thread newThread = new Thread(() -> {

        .
        .
        .
        .
        .

          });

          newThread.start();

        .
        .
        .

          return "redirect:/admin_roles_single/" + uid;
      }
  }

I will try to do it with GET method.

EDIT: just changing request to GET solved whole problem. Thank you a lot @LEDfan

Nice to heart that the problem is solved now. I’m therefore closing this issue. Feel free to open a new issue if you encounter anything.
